First EI reporting period includes last day of work

I just did my first report for EI earlier today and while looking back on the payments they submitted, I realized my actual last day of work was in the 2 weeks of reporting that I submitted today. So I understand I made the mistake of saying no to "did you work during the period of this report?"

So I was going to contact Service Canada in the morning since they aren't open right now but I noticed in Week 1 Reporting payment, it includes "earnings in your last week of work" and is a lower amount than the week 2 (no work at all this period).

I think I'm still going to contact Service Canada tomorrow, but this makes it seem like it got my last day of work in my ROE. Did they already get that last day of work?

My first week was June 22 - 28 and my last day of work (as listed on my ROE) was the 24th and that was the only day I worked that week.
